I have a host machine (win server 2008 R2) with several Hyper-V virtual machines. I want to be able to redirect certain ports of host to virtual machines.
There is virtual network connection between host and virtual machines ( Host is also attached to external network ( Virtual machines have several other networks between them.

E.g., I want to be able to redirect traffic from 12345 to 54321

I tried RRAS in windows server but for it to work Default gateway to has to be set in virtual machines. Virtual machines can not be on external network.

You need to have router (or server) on public 10.10.10.x subnet, that has also lan interface in subnet 192.168.10.x , so than you need to do NAT and port forwarding.

So which router do you have currently that connects this subnets? cisco ? RRAS ?
